The room depicted in this work has two chandelier mounts but no chandeliers. Its background features a nun and a bodyguard conversing on the right and a man in black standing, knee bent, in the doorway. Two dimly-lit Rubens paintings hang on the back wall, along with a mirror reflecting two figures. This painting's left side is occupied by a man with a red cross on his shirt and a large canvas; that man is the artist himself. In the right foreground, a dog serves as a footrest for a dwarf, while on the left, one of the title figures offers a drink to the Infanta Margarita.  For 10 points, name this painting, a work of Diego Velásquez.
